This is also flaky in GTK and WPE with the same exact output and regression profile, so it's definitely a cross-platform bug. Updating expectations... The bot wpe-release completed 980 runs on the interval [302277@main-306273@main] Frecuency of results for test: imported/w3c/web-platform-tests/fullscreen/api/element-ready-allowed.html 695 times [70.9%] -> NOERROR 170 times [17.3%] -> TEXT PASS 115 times [11.7%] -> TEXT Of those 980 runs it didn't match the expectation 285 times [29.1%] Details of the type and frequency of unmatched expectations: 170 times [17.3%] -> TEXT PASS (Expected: PASS) 115 times [11.7%] -> TEXT (Expected: PASS) Flakiness factor: 43.6% - This test was flaky on 43.6% of the 980 runs analyzed, either giving different results within a single run, or a different result than in the previous run.
